Tree view corresponding to the higher scores (E. value threshold: 2e-99) of a BLAST pairwise alignment of the submitted Ole e 1 sequences within the nr databases. Ole e 1 sequences of the same cultivar origin are frequently grouped in the same branch of the tree. Distances among some olive cultivars (i.e. Picual and Bella de España) were in some cases larger than between olive cultivars and Ole e 1-like proteins from members of other genera of the Oleaceae family (i.e. Bella de España and Fraxinus/Ligustrum).
